PROTECTOR FOB ENGINE HOODS.

Application m d February 9, 1920, Serial No. 357,332. Renewed. December15, 1922.

To all whom it may concern:

Be it known that I, BERNHARD Hess, a citizen of the United States,residing at Forest Park, in the county of'Cook and State of Illinois,have invented new and useful Improvements in Protectors for EngineHoods, of which the following is a specification.

This invention relates to improvements in protectors for engine hoods.

The hoods of automobile engines frequently are provided at their sideswith openings for the admission of air into the interior of the hood,this admission of air in a predetermined direction being facilitated byflanges projecting outwardly and partly overlapping the openings in thehood.

An object of the present invention 1s to provide a protector which canreadily be attached to an engine hood for closing these openings toprevent the admission of air therethrough, and to prevent thereby afreezing of the cooling fluid which during the operation of the engineis circulated through a jacket of the engine.

It is also an object of the invention to provide a readily removableclamp for securing a rotector plate of this character to the wal s ofthe hood, and to render this clamp as little conspicuous as possible soas not to detract from the characteristic appearance of the respectiveengine hood.

It is also an object of the invention to provide a clamp and protectorof this character which can readily be secured to the wall of the enginehood without interfering, after its attachment, with the opening of thiswall.

With these and other objects in view an embodiment of the invention isillustrated in the accompanying drawing and described in the followingspecification.

In the drawing:

Fig. 1 shows an engine hood in side elevation, with the protector latesecured to the inner surface of the wa Fig. 2 is, on an enlarged scale,a horizontal section through this wall and protector plate, and

Fig. 3 shows perspectively a portion of the rotector plate and clamp.

The side wall 1 of the hood is provided with a plurality of slots 2,over which project louver portions 3, which are spaced from the plane ofthe wall at their free edges, but which merge into said wall at theirouter edge. They permit the admission of am through the slots 2 in apredetermined direction.

In order to prevent the admission of air through the slots 2 inextremely cold weather, a protector plate 4, made of suitable sheetmaterial, as metal, card board,

wood or fiber, is detachably secured to the nner surface of the wall.The attachment 1s efi'ected in the present embodiment b means of clampswhich are held to the wall 1 through the slots 2 thereof.

The clamps 5, in the present embodiment, are made of a single piece ofwire or the like adapted to hold the protector plate detachablyagamstthe inner surface of the hood, owing to the resiliency of the materialof wh1ch they are made. The clamps comprise rubber covered holdingportions 6, bent at approximately right angles from hood and platetraversing portions 7, from which angular arms 8 project oppositely invertical direction. The angle which the arms 8 normally form with thehood traversing portions 7 is somewhat more acute than shown, so that inthe application of these clamps a slight deformation of these anglesoccurs. Alt ough the inner ortions of these arms 8 are spaced from t 6protector plate, the outer portions of the same are forced to restagainst the protector plate, and as the clamping portion 6 is held inengagement with the outer surface of the hood it is obvious that theouter ends of the arms will force the protector plate into engagementwith the inner surface of the wall.

For the purpose of increasing the leverage with which the arms act onthe protector plate, the point of engagement of said arms with theprotector plate is at a relativel large distance from the slots 9,throng which the traversing portions 7 of the clamp pass through theprotector plate. This frictional engagement of the outer ends of thearms with the outer portions of the protector plate is furthermoreenhanced by the formatlon of longitudinal arms 10 bent at approximatelyright angles to the first mentioned arms 8 and lying in engagement withthe protector plate.

. When it is desired to attach a plate to the inner wall of the hood theclamp is passed through the longitudinal slot 9 of the and brought intoengagement with a portion of the wall of the hood on the outsidethereplate of. This will then firmly hold the outer ends of the arms inengagement with the protector plate; and, owing to the resiliency of thematerial, this engagement will be maintained until the clamplng portionson the outside are again shifted into a position in which they can bewithdrawn automatically through the slots in the outer wall and throughthe longitudinal slots in the inner wall of the plate. The length of theslots 9 permits of suitable adiustment with respect to the wal I claim:

1. In combination with the wall of an engine hood having perforations, aprotector plate secured to the inner surface of said wall and coveringsaid perforations, and detachable clamps extending through saiderforations and removably holding said p ate to said wall.

2. In combination with a wall of an engine hood, a protector plate, thewall of the hood being provided with openings, and the protector platebeing adapted to cover said 0 enings, and a one-piece clamp exten ingthrough one of the openings of the engine hood and engaging the outerside of said engine hood and the inner side of said plate.

3. In combination with the wall of an engine hood having perforations, aplate secured to said wall and coverin said perforations, and aone-piece clamp aving a portion engaging the outside of the engine hoodand other portions engaging the inside of the protector plate, sai lastnamed portions being forced into engagement with the protector platethrough the resiliency of the material of which the clamp is made.

4. A one-piece clamp for protector platw of the plate of engine hoodscomprising a wall-engaging portion, a wall-traversing portion, an armsextending from said wall-traversing portion in opposite directions intoengagement with said plate.

5. A one-piece clamp for fastening protector plates to en ine hoods,said engine hoods clamp consisting of a wall-engaging portion, awall-traversing portion, bent at up roximately right angles to saidfirst named portion, and plate engaging arms extendin from saidtraversing portion in opposite d1- rections into engagement with saidplate.

6. A one-piece clamp for securing rotec-= tor plates to the walls ofengine hoo s, said walls being provided with perforations, said clampconsisting of a wall-engaging portion, a wall-traversing portionextending through a perforation, arms extending from said last namedportion angularly into engagement with said plate, and fingersprojecting angular-1y from said arms "in engagement with sai late.

7. In a evice of the character described, a plate having an opening anda clamp having one portion engageable with the part to which the plateis to be secured, and another portion projecting through an openin inthe plate, and arms extending from sai last named portion to a pointremote from said opening. 1

In testimony whereof, I have afiixed my signature, in the presence oftwo witnesses:
